SHINGLE-MACHINE.

Specification of Letters Patent No. 5,762, dated September 12 1848.

To all whom t may concern i Be it known that I, MILES R. PAYNE, of WValdo, in the county of Delaware and State of Ohio, have invented a newand useful Improvement on My Patented Machine for Cutting Shingles,which is described as follows, reference being had to the annexeddrawings of the same, making part of this specification.

Figure l is a top View of the machine. Fig. 2 is a plan of thedouble-inclined plane vibrating setting bar and the cent-ral timber ofthe frame, to which it is attached. Fig. 3 is an end elevation of themachine, showing the setting arm at-tached to the vibrating panel. Fig.t is an elevation of the clamp. Fig. 5 is a sectional view of the knife.

Similar letters in the several figures refer to corresponding parts.

In the use of my former machine for cutting shingles, laths, &c.,patented on the 30th day of October, 1840, I experiencedmuch diiiicultyand inconvenience in cutting shingles by the use of two parallel rests,

I placed at a given distance apart, between which the shingle bolt wasplaced, which.

limited the machine to the recept-ion of a given sized bolt, betweenthem; and consequently limited the size of the shingles to be cut, onaccount of there not being room between the rests, wit-hout a previousadjustment of one of them, for the admission of large bolts and when asingle knife was used having no means of cutting the butts and pointsalternately-the bolt being supported on the sash which moved in the sameplane and having no vibratory panel, or other contrivance for adjustingt-he bolt for cutting the but-ts and points alternately in oppositedirections, this being effected by a particular arrangement of the twoknives on the sash.

I have now invented an apparatusfor setting the shingle bolt for havingthe shingles cut therefrom with the butts and points in oppositedirections alternately, said apparatus consisting of a vibratory wedgeshaped bar arranged and combined with the bed of the machine; and aT-shaped plate fastened to and combined with a vibratory panel, the partof which at right angles to the panel being made like a knife with twosharp edges and slightly elastic and which part is caused to come incontact with the sloped sides of the said vibratory wedge shaped bar ateach movement back and forelastic setting arm, in combination with theother parts ofthe machine constituteswmy new invention and improvement,for which r I now solicit Letters Patent. p

The frame A, sliding sash B, obliquel knife O, vibratingpanel D, forvsustaining the shingle bolt and moving on center pins in ythe sash, theparallel ribs for gaging the' thickness of the shingle and upon whichthe bolt is placed, the sliding dogs Gfor holdying the bolt during theoperation of cutting" the shingle and slidingin openings in theframe,`the springs H for moving the sliding dogs toward the bolt beingall made and arranged in the manner represented in the anneXed drawings,or, in any convenient way, renders a more particulardescription ofthese'several parts unnecessary.

The double inclined plane setting bar J against which the doubleedgedelastic. settingl arm K connected to the vibrating panel D,strikes, for vibrating and holding the panel in the required position,is made of steel or other suitable material in the form of a wedge witha thin elastic point, having avert-ical bolt I passed through it nearthe middle and into the central bed piece A of the frame and on which itvibrates in the manner and for the purpose hereafter described.' Thebutt end is clamped or embraced by a clampL just so tightu as to causeit to move with the requisite degree of friction vand to hold it frommoving while the elastic setting arm K is moving against it from thebutt end toward the elastic point as the sash is moved forward with theknife toward the bolt. The tapered portion ofthe setting bar from nearthe fulcrum to the point Ais made slightly elastic vso that it will Theclamp L is a bar of wood, or metal,

having a notch Z cut in its under side which admits the butt end of thesetting bar, the shoulders Z, Z, forming stops against which the buttend of the setting bar strikes alternately during its vibratoryhorizontal motion. The setting arm K attached to the vibrating panel forvibrating the same in cutting shingles is made thicker in the middlethan at its two edges which are made like a double edged knife, as shownat K Fig. 5. It is connected to a metallic plate lVI screwed, orotherwise secured, to the panel D and has sufiicient elasticity to yieldor give when it comes in contact with the setting bar J, and continuesto yield, or bend, until the said elastic setting arm K has passed bythe center of the setting bar,` in running back the sash; and has comein contact with the larger portion of the bar when the pressure of thesetting arm increases to such a degree as to cause the bar to vibrate onits center I and bring the butt end lagainst the opposite shoulder orstop Z in the clamp L and the elastic point of said bar against theopposite fixed cog or pin P inserted into the bed piece A of the frameupon which the bar vibrates.

The operation of my improved machine is as follows: The shingle boltsbeing properly softened by steaming, or otherwise,`and the sash with theknife putin motion in the usual manner, by any convenient power,^thebolt is placed upon the ribs CZ Z of the vi-A brating panel D betweenthe dogs G Gr which yare driven into or against -it bythe springs I-I H,the panel being inclined tothe required angle to form thertaper oftheshingle.

The sash' B, advances with the knife C, takes ofi a shingle of therequired taper which passes through the opening below the knife to asuitable receiver', thesash i carrying the knife beyond the bolt and atthe saine time carryingthe setting arm K past the small end of thesetting vbar J J. The sash is then moved in an opposite direction, thebolt remaining between the dogs Gr Gr and resting upon the end of thesash, until the knife passes from under the bolt the setting arm at thesame time coming in Contact with the opposite side of the setting barand bearing against it with a gradually increasing pressure until itpasses beyond the central bolt I on whichit vibrates; when itsvincreasedpressure causes the setting bar lto vibrate, the panel being caused tovibrate simultaneously with the movement of the setting bar by theaction ofthe setting arm attached to the panel and in contact with thebar as aforesaid. The sash is again moved forward toward the bolt takingoff another shingle having its point in an opposite direction from thatof the shingle previously cut. On the arrival of the setting arm at thesmall end of the setting bar it passes by it to the opposite sidethereof. The sash is then carried back to the opposite end of the frameand in thus running back t-he setting arm is caused to act on the sideof the setting bar to which ithas previously passed and acts on thisside in the same manner that it acted on the and, the panel to vibratein a contrary direction; and in this manner` the action of the machineis kept up causing the setting barV and panel to vibrate simultaneouslythe former horizontally and the latter vertically, as the sash is movedback for a repetition of the cut, the setting arm holding the panel frommoving during the operation of putting by its bearingagainst the settingaar. i

The-machine thus arranged and operated becoinesself setting in regard tothe position of the bolt for cuttingthe shingles with the but-ts v andtipsA in alternate order to the right, f&c., left. I

What I claim as my invention and desire to secure by Letters Patent is-The combination of the Wedge shaped vibrating setting bar J J and springsetting arrn- K arranged and` operated in the manner and for thepurposeset forth;

In testimony whereof I have hereunto signed `my name before twosubscribing witnesses this 24th day of November 1847.
